Research Interests

Water is essential for our life. Thus, the sustainable safe water supply is one of the missions of the urban water infrastructure. As stated in the Goal 6 of the Sustainable Development Goals (SDGs), there still exists many regions with the inadequate water supply system.
Water supply issue can be interpreted from the two aspects, namely, financial aspect and water resource quantity aspect. Many non-urban areas or rural areas in the developing countries with the limited financial resources are lacking safe water supply, and the improvement of the water supply system is the prime task for achieving SDGs. On the other hand, in countries with the limited freshwater resource, such as Middle East countries, or parts of Australia and United States, the utilization of sea water or treated wastewater as water resource is high priority.
To address these water supply issues with various background and situations, our research focus is on the water supply system with membrane filtration technology, which can efficiently remove the pollutants and pathogenic microorganisms, and can produce safe potable water. One example of the membrane filtration applications for developing countries is the point-of- use (POU) type gravity-driven membrane filtration system, which enables the sustainable safe potable water supply without electricity supply and periodic maintenance. Control and removal of pathogenic microorganisms by membrane filtration in water purification or wastewater potable reuse is another our research target.
Furthermore, since the water infrastructure in the developed countries including Japan faces ageing, how to maintain the sustainable water supply has become the critical issue lately. Thus, we are also developing the method for diagnosing and predicting of the ageing of water purification system.
